The best way to punctuate the bolded portion of the quotation is:
c) them”.—C.S. Lewis
Explanation:
According to the MLA format, periods, commas and semicolons should be placed after the parenthetical quotation. Punctuation marks like question marks and the exclamation marks should appear in the quotation marks in case if they are also a part of the passage. If they are not a part of the passage, they should be placed outside the quotation marks.
Wallace places emphasis on the word "adjust" because he is addressing our realities and way of thinking as "default." He expresses the importance of paying attention to your surroundings, and adjusting to other perspectives and ways of thinking. He compares our ignored experiences to the water fish swim in but were never taught to notice.
